Return-to-Home (RTH)

Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three
types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios
in detail.
GPS
Home Point
The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and
lighting conditions are sufficient. The aircraft will automatically climb up to avoid obstacles and
descend slowly as it returns to the home point. To ensure the aircraft returns home forwards, it
cannot rotate or fly left and right during RTH while the Forward Vision System is enabled.
Failsafe RTH
The Forward Vision System allows the aircraft to create a real-time map of its flight route as it flies. If the
Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be
automatically activated if the remote controller signal is lost for more than three seconds. The aircraft
will plan its return route and retrace its original flight route home. The aircraft will hover for 10 seconds
at its current location. When it regains signal connection it will wait for pilot commands. The Return-to-
Home process may be interrupted and the pilot given control of the aircraft if the remote controller signal
connection is re-established.

Aircraft cannot return to the Home Point when GPS signal is weak or unavailable.
Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 65
feet (20 meters) radius of the Home Point. Aircraft will stop ascending and immediately return
to the Home Point if you move the left stick if the aircraft reaches 65 feet (20 meters) altitudes or
beyond during Failsafe.
The aircraft cannot avoid obstruction during Failsafe RTH if Forward Vision System is disabled.
It is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app,
enter "Camera" and tap
User cannot control the aircraft while the aircraft is ascending to 65 feet (20 meters) from the
current altitude. However, user can press RTH button once to exit ascending and regain control.
If a strong GPS signal was acquired before takeoff, the Home Point is the
location from which the aircraft launched. The GPS signal strength is indicated
by the GPS icon ( Less than 4 bars is considered a weak GPS signal). The
aircraft status indicator will blink rapidly when the home point is recorded.
